How long do oil and gas producers need to go from drilling to production, Investopedia

Depending on the depth of drilling required and the type of drilling method used, a standard oil well can commonly advance from drilling to the beginning of production for an oil company within one to three months. However, drilling to production is only the last phase of work for an oil producer. The preceding steps take a substantially longer time period and involve major capital expenditures.

There are basically three phases of oil production:

Pre-drilling Oil Activities

The longest and typically most expensive phase is pre-drilling activities – all the things that an oil producer vereiste do before even thinking about doing the actual well drilling. Pre-drilling activities can take half a year or more. They include doing the necessary seismological surveys to locate a promising drilling webpagina, obtaining land and sometimes separate mineral rights, getting required permits and regulatory approvals, creating infrastructure such spil building access roads to the webpagina and providing for water and electro-stimulation, and trucking te all the equipment necessary for drilling and production.

The last pre-drilling activity – mapping out the well padachtige boundaries and werkonderbreking out the well – can take an extra one to two months.

Drilling Oil

Drilling itself occurs te two phases: drilling down to below the water table and then encasing the well crevice ter cementlaag to prevent groundwater and soil contamination, and then drilling to the required depth and taking the necessary steps to stimulate upward oil flow.

The drilling method chosen or necessary to access an oil field can affect the cost and time required for drilling, and also determine how much oil can be cost-effectively recovered from the webpagina. For example, if horizontal well drilling is used instead of standard vertical drilling, this can often dual the total cost of drilling and the time required to stir from drilling to production. On the positive side, however, horizontal drilling can potentially enable the oil producer to recover up to four times more oil than could have bot accessed with conventional vertical drilling.

Oil Production and Transportation

After oil is extracted from the ground during the production phase, the raw materials extracted such spil liquid hydrocarbons, gas, water and solids, are separated and divided into contents that can and cannot be sold. Oil is then processed at a refinery to eliminate any other impurities.

Depending on the quantity, oil and gas producers can vrachtvervoer oil by land or by sea. For constant supplies on a long-term voet, pipelines have become a better option for economic reasons. The use of pipelines is fine when moving oil within the boundaries of a single country or two countries with strong sociopolitical and economic ties such spil Canada and the U.S., but it can be troublesome when passing through several nations, especially those with political problems.

For example, the ongoing hostilities inbetween Russia and Ukraine overheen border territories had resulted te the scrapping of a pipeline project that would have assured a constant supply for European Union countries.

For countries that have no access to pipelines, the wegtransport of crude oil to refineries is usually done via tankers. Thesis are ships with enormous reservoirs that have substituted the barrels used te previous eras. Lately, super tankers that carry up to 200,000 dead weight tons of oil omschrijving to 1 million barrels of crude oil have bot plying the open seas, but not all harbors are capable of permitting entry to thesis giants. Other vrachtvervoer options still ter use include specially made trucks and the age-old means of using barrels to wegtransport oil via railroad.
